Mikkel Kessler has promised "pure action and adrenaline" when he renews his brutal rivalry with Carl Froch at London's O2 Arena on May 25.

The world super-middleweight champions - Kessler holds the WBA belt, Froch the IBF - will collide in one of the year's most eagerly-awaited fights after sharing 12 brutal rounds in April 2010.

Kessler, from Denmark, edged an unanimous points decision on home soil on that occasion and has agreed to travel to London for a rematch that he predicts will underline his superiority over Froch.

"Just look at the fan interest and how fast the tickets have been selling," said Kessler, in reference to the near-sell out at the O2 Arena after 15,000 tickets were bought on the first day of sale.

"The fans really want to see us go at it again because they know it will be a war.

"No holding, no head-butting, no clinching. Just two warriors going at it from the first bell until the very end. It will be pure action and adrenaline.

"Carl came to my country, now I am coming to his country. I owe him that. I have fought and travelled all over the world, so I look forward to facing Carl in his back yard.

"On May 25 two true champions will clash. And I will be the winner again."

The rivals came face to face in Copenhagen on day two of their media tour with Froch adamant that Kessler will be his 31st victim.

"It's going to be a toe-to-toe fight, it will be vicious and brutal. This is a fight that could go either way, but I know that I will win. He beat me the first time, no excuses, but May 25 will be different," Froch said.

"I will throw punches at him from the first bell and honestly I think that will be too much for him to handle.

"I know that he will not grab or hold but fight fire with fire and come right back at me, so the fans will be in for a real treat.

"We had a good two-day press tour, the interest is huge in the UK and in Denmark and that is what boxing at the top level is all about."
